Joe Biden is just demolishing President Trump if you believe the latest national poll. There’s a good reason to think this won’t last though.

Former Vice President Biden leads President Trump 50% to 39%, according to the latest poll by Quinnipiac University, whose polling operation is nationally renowned. (If you’re wondering, Quinnipiac’s late-May poll in 2016 showed Hillary Clinton leading Trump by 2 points, which ended up being her final margin of victory in the popular vote.)
